From your very first sentence it seems you don't actually have much of a clue how the stock market works in reality...
I wish I never encounter such a disgusting, god forsaken, rampant, brutal and bs market. Btw mistake is made, lesson learned. I wish the future generation having better luck on not getting financially ruin by even more of this "old man tricks" pump and dump market and more and more horror stories come across all over the news or confession. But it’s not easy, good and decent and innocent human being are often fall victim into such tricks, just as easy as how they fall into the love poison in real life. Look thing is new when many still easily fall prey into it in 2000 and 2008, causing 9/11 incident and lehman, which is just a revenge in disguise.
